ABSTRACT:
Provided is a semiconductor memory device and a driving method for initializing an internal logic circuit within the semiconductor memory device under a stable state of a source voltage without an extra reset pin. The semiconductor memory device includes a power-up signal generating unit for generating a power-up signal; an internal reset signal generating unit for generating an internal reset signal in response to a pad signal inputted from an arbitrary external pin during a test mode; an internal logic initializing signal generating unit for generating an internal logic initializing signal based on the power-up signal and the internal reset signal; and an internal logic unit initialized in response to the internal logic initializing signal.
